Hey small guy, it's good to know that you are doing well apart from your stress related wrinkles. I guess I can advice you based on my personal experience. I am 33 now I look as if I am in my 20's. I always get comments about how radiant my face looks. But it was not always the same until 4 year back when I was looking much older for my age as if I am in 35 to 40 range. Now let me put down the points which I believe are the reason for my drastic change
1. I was not always obese but had put on weight for 4 years since I gave up my smoking 8 years back. giving up my smoking probably improved my skin texture but I was looking older as I was getting obese. I started to reduce weight with proper diet and I stated looking younger
2. I meditate daily and it guess that brings glow on my face - don't know.
3. I take cold water bathing even in the winter. That sounds crazy but I feel that keeps my body fit and active. I am in India at the moment with the family, but used to take cold bathing when I was in London as we'll
4. I don't drink coffee, tea and avoid any sugar related products
5. I don't used to work out before, but now I do aerobics in gym, not regularly though
6. I use Loreal hydra energetic face cream
7. Don't masterbate. There is lot of content on net that link facial glow and youth to no masterbation. Of course you can have sex.
Recently I had been to a marriage and had so many comments from my distance sisters how smart I look. I am married with and my wife says the same. For last 4 years my friends who had seen me before when I was obese has commented on how radiant my face is with a glow. I guess all this was possible due the attributes give above. Give it a try.
And one more thing, if you have reduced weight drastically after surgery wrinkles will appear due to weight loss. Give some time for your skin to adjust and it does, then you will be alright. Take care
